2. Make sure the export directory is exported via NFS entry in /etc/exports. For
example:
/install/RHEL5.2 *(ro, async, no_rootsquash)
3. Then restart the NFS daemon with:
/sbin/service nfs start
/sbin/service nfs reload
Virtual optical device setup and installation
This installation option uses the virtual optical device on the Integrated Virtual
Manager (IVM) to perform a CD/DVD installation of a Linux operating system
image. The Linux image is stored in the IVM’s virtual media library. Follow the
steps given in 4.6.4, “Optical and Tape devices” on page 132 to copy the
CD/DVD image onto the VIOS virtual media library. Once the CD/DVD image is
copied onto the VIOS hard disk, assign the virtual optical device to the LPAR.
The install process is the same as in 8.2, “Linux LPAR installation using DVD” on
page 337 for Red Hat Enterprise Linux and 8.3, “Linux network installation
(detailed)” on page 341 for SLES, but remember to select the virtual optical
device as the boot device in the SMS menu and not the physical media tray.
This installation is much faster than a traditional CD/DVD installation. The other
benefit is that a read-only image in the VIOS media library is concurrently
accessible to all the LPARs on the same IVM so you can run simultaneous
installations of an operating system.
Note: PowerVM must be installed and properly configured on the JS23
BladeCenter for this to work.
